$66 - 8 foot diameter weather balloon$150 - ~300 cf of He and cylinder rental. You could also build an electrolysis rig and crack your own hydrogen for about the same amount.$50 - Used android based cell phone with a camera and GPS enabled.$5 - Ball of nylon string.$5 - Some chemical hand warmers to keep the camera warm and happy.$10 - A used styrofoam box and packing tape to build your enclosure. Don't forget to build a "stage" out in front of your phone's camera aperture opening for putting odd objects to video "in space".$20 - for the "Where's My Phone?" GPS tracking app (so you can find where it landed after its flight) and one for doing long videos or timelapse. Or I guess writing your own.

So what is that? $306. of course you would get cheaper per flight costs if you did more than one, but I imagine chasing them down would get old fast, and you might annoy the local authorities...

You mean like JP did for the Toshiba commercial? Well, it was a normal chair, not a lawn chair, but other than that it's been done already...

While there have been manned high altitude balloon projects, including skydiving, we are talking about improvised personal attempts. Which I think might cause trouble, not only for the "Hey Ya'll, watch this!" individual, but also with the overall New Space and sub-orbital space environment if someone kills themselves or causes an aviation accident.

A bit beyond the scope of this thread, but its the natural progression of the development of this activity.

Ah, your statement was ambiguous . I seems that this has been done as well, though not to those altitudes. You'd need a space suit and a lot of balloons I guess...
